INTRODUCTION Several factors are used to stratify the probability of polyp recurrence. However, there are no studies correlating the location of the initial polyps and the recurrent ones. The aim of this study was to verify whether the polyp location at the surveillance colonoscopy was correlated with the location of the previously excised polyps at the baseline colonoscopy. METHODS A retrosp...
UNLABELLED As acidic monomers of self-etching adhesives are incorporated into dental adhesives at high concentrations, the adhesive becomes more hydrophilic. Water sorption by polymers causes plasticization and lowers mechanical properties. The purpose of this study was to compare the water sorption and modulus of elasticity (E) of five experimental neat resins (EX) of increasing hydrophilicity...
A new result enables direct calculation of thermoelastic damping in vibrating elastic solids. The mechanism for energy loss is thermal diffusion caused by inhomogeneous deformation, flexure in thin plates. The general result is combined with the Kirchhoff assumption to obtain a new equation for the flexural vibration of thin plates incorporating thermoelastic loss as a damping term. The thermal...
INTRODUCTION The aim of this paper is to introduce the flexure topology of a new, high fill-factor (99%) micromirror array (10,000 1mm 2 mirrors) that can achieve continuous, closed-loop control of three degrees of freedom (DOFs)—tip, tilt, and piston—over large ranges (>±10 o rotation and >±30μm translation) at high speeds (10’s of kHz). The flexure topology of this array was designed using th...
OBJECTIVE To (1) determine if histologic scores of pelvic flexure biopsies can predict short-term survival in horses with large colon volvulus (LCV) and (2) identify clinical variables predictive of short-term survival. STUDY DESIGN Case series. ANIMALS Horses (n = 28) with LCV (≥ 360°). METHODS Medical records (January 2000-February 2008) of 28 horses were reviewed and clinical data reco...
BACKGROUND The cancer of the splenic flexure of the colon is a rare medical entity with severe morbidity because of its insidious onset. METHODS We present the case of a 59-year-old male patient with dull left upper quadrant pain, leukocytosis, and anemia. A splenic abscess described as an air-fluid level with splenocolic fistula was found on CT scan imaging. Surgery was done for splenic pus ...
